- When acknowledging interrupts, write the value 0xff to the interrupt
  status register rather than 0.  Without this, a single hardware volume
  event triggers an interrupt storm.
- Implement hardware volume control for the Maestro chips.  This version
  only handles the case where both channels are adjusted at the same time.
